This Guide is to melt down one or two champions in max. 6 seconds

Skillorder is R->2->3 on default Keys/Talents
(Shadow Assault 6s -> Gab-close max 1s -> Searing Attacks before initial blow -> Berserk)
Results in ~700 AD per AA by 1.51 AS on lvl 20 (without Seasoned Marksman stacks)

Use Vorpal Blade if the enemy used his escape or to doge CC skillshots but never Blink (our escape)

This Guide is more for low health targets and versus skillshot heavy champions (and FUN).

Usage is very variable but situational.
(consider less damage later on)

use Blink for triggering the Follow Through passiv too (but dont burn your last escape)
Youtube video soon because reasons and request

so on "Confuse the enemies !" ... or yourself.

This Guide is to maximize Focused Attack and Follow Through.
(Regeneration Master is not recommended on small maps)

use Autoattacks (AA) between skills like Q -> AA -> W -> AA ( -> W -> AA)

Advanced:

The W can cancel the Q Animation.

you can queue up skills for burst damage thats released in 1 second like:
hold [shift] and move to any location - while holding [shift] press some skills

Example:
hold [Shift] + Move
(before reaching the destination)
hold [Shift] + W + Q + W + E
(with Rewind)
hold [Shift] + W + Q + W + Rewind + W + Q + W + E
(you can use Blink before and after Rewind to engage/disengage but not the "second Wormhole blink")

Some champions can trigger the queue with skills like Tyrande's Q unfortunately not Zeratul.

My MMR is currently at 3032 @ Rank 4 and yes English is not my native language.
